MACHINERY FOR FORI/LING WEBS or OLOTH OF WOOL, HAIR, sw., WITHOUTSPINNING OH WEAVING.

Speccation of Letters Patent No. 66, dated October 20, 1836.

To all whom t may concern Beit known that we, JoHN ARNOLD and GEORGE G.BISHOP, both of Norwalk, in the county of Fairfield and State ofConnecticut, both native citizens of the United States, have invented anew and useful improvement on the machine heretofore invented andpatented by the said JOHN AR- NOLD, for forming the web for cloth o-fwool, hair, or other suitable substance without spinning or weaving,patented July 15, 1829.

The imperfections in the machine patented as aforesaid, and which it isthe object of our improvement to remedy arelst the doffer, and aproncylinders of the pat ented machine having equal motion as warp, and weftaccumulate upon the apron, and around the cylinders until a suiiicientthickness is obtained the surface of each succeeding layer, is more, andmore eXtended, and its motion proportionally increased so that thecrossing weft will no longer cover the whole, and the Work becomesuneven, to remedy this defect, and as an im provement on said machine weplace upon the shafts of theJ doffer, and apron cylinder, matched conesgoverned by a movable belt in the same manner, and producing the samewell known effect as matched cones in common use to regulate thevarying, and relative motions of the cotton Speeder by means of whichthe relative motions of the doffer and apron cylinders will varyaccording to the varying extent of surface around the carrier, and thusmake even, and perfect work; 2d, wool, and hair being elastic and thedifferent kinds of different elasticity it had been found very ditlicultif not impossible to work wool or o-ther material possessing muchelasticity on the patented machine on account of rits springing underthe fullers, in consequence of which the sheets of weft become folded,or contracted and will not retain an even Width. To remedy this defect,and as an improvement on said machine we substitute combs in place ofthe fullers described in said machine, which we call faller combs. Thesecombs are Of the same form as the chain combs, described in said patent,and are connected with the same levers which support theV faller rods byarms attached to each. The movement of the faller combs adopted in thisimprovement is also different from the movement of the fallerrods in thepatented machine in this. The rods rose gradually, and fell suddenlyupon the weft. The faller combs are at rest until the moment in whichthe chain comb, and doffer are ready to deliver the weft when they riseby force of a cam Or pin upon the same levers, and receiving the weftfrom the chain comb and dOft'er and carry it down by an easy motion anddeliver it on the warp, clearing themselves by a pin and spring in thesame manner as the chain combs clear themselves as described in the Saidpatented machine, being retarded in their downward movement by a springor suspended weight to prevent their sudden descent. This spring may bea spiral spring hung from above or a cord from a spring pole governingthe descent more or -less gently as different materials may require.

That these improvements may be more clearly understood, we refer to-thedrawings with references to these improvements accompanying thisspecification as part thereof.

That we claim as our inventionand improvement and desire to secure byLetters Patent is- 1. The application of matched cones governed by amovable belt to vary the relative motions o-r speed of the dof'fer, andapron cylinders as the varying extent of surface around the carrier isextended by the increasing thickness of the web, as specifiedr above.

2. The substitution of the faller combs with the machinery to regulatetheir movement as above described, instead of the fallers or faller rodsdescribed as part of said patented machine, and these improvements weclaim in joint and several combination with the other parts Of saidpatented machine, and therefore we solicit Letters Patent.
